《Tetrabiblos》Knowledge May Be Acquired By Astronomy To A Certain ExtentClaudius Ptolemy（Ashmand 英譯 1822）
The art of navigation, for instance, is not rejected, although it is in many points incomplete; therefore the bare fact that predictions are frequently imperfect cannot authorise the rejection of the art of prescience: the magnitude of its scope, and the faint resemblance that it bears to a divine attribute, should rather demand grateful commendations, and receive the utmost regard and attention.
